utilizo esto: use Greenter\Model\Sale\Document; use Greenter\Model\Sale\Invoice; use Greenter\Model\Sale\SaleDetail; use Greenter\Model\Sale\Legend; use Greenter\Ws\Services\SunatEndpoints;

 public function generar_comprobante($invoice)
{
        $util = Util::getInstance();
        // Envio a SUNAT.
        $see = $util->getSee(SunatEndpoints::FE_PRODUCCION);
        $res = $see->send($invoice);

        if ($res->isSuccess()) {
        $cdr = $res->getCdrResponse();
        $nexus = "|".$util->getResponseFromCdr($cdr);    
        $this->sms = "correcto".$nexus;

        Util::writeXml($invoice, $see->getFactory()->getLastXml());
        $pdf = $util->getPdf($invoice);
        $util->showPdf($pdf, $invoice->getName().'.pdf');  
        Util::writeCdr($invoice, $res->getCdrZip());                               
        } else {
        $this->sms = $res->getError()->getMessage();
        }
        return $this->sms;
}
